Study on the Agronomic Characteristicks in Native Varieties , Maie Sterile and Indred lines of Sorghum
수수재래종 웅성불임 및 자식계통의 생육특성에 관한 연구
Abstract
For the forage sorghum breeding, 22 American M.S. lines and 58 inbred lines were sown in pots, and 80 local varieties in field in 1978. Their agronomic characteristics were as follow; 1. All of the tested lines/varieties were headed from 22nd to 26th of July. Varieties of 69-86% were headed from 17th to 31st of July. All of lines/varieties began their flowering within 3-5 days after heading and native varieties had wide variance in heading and flowering. 2. The plant height of M.S. lines, inbred lines and local varieties were 86-114 cm, 81-190 cm and 142-289 cm, respectively. Leaf blade length of M.S. lines and inbred lines were ranged from 52.2 to 53.4 cm and local varieties 70.7 cm. Average stem diameter of M.S. lines and inbred lines were ranged from 8.81 to 7.74 mm and local varieties 11.3 mm. 3. Stem diameter were significantly correlated with leaf length and leaf blade width. The internode length were also significantly correlated with plant height. Especially, all characteristics in local varieties were correlated with each other.
